Don't worry about that is not your fault Peter.
I have asked your for the wiring diagram because in my motorbike there are no wire harness for Usb auxiliary plugs,2014 model. I was plannig to make one.
I will use the original aux sockets wich are mounted to instrument claster, and mont new resistor under the seat, make new cables and job done.
If you want you could use the original harness to install new 2A or 3A resistor.
I have already bought one on eBay named:
Dual Double 2 USB DC-DC Car Converter Module 12V To 5V 3A 15W Power Adapter
The best ask someone to do for you incase your do mistake like me :-)
